Thanks!
Depends on the dealership. If Dinan-authorized then Dinan no and JB4 questionable since they might not care. I know my dealership in San Antonio will go nuts if they see my JB+ so very yes for me. JB4 is cheaper. ~640 (with bluetooth) vs 899 Dinan. Probably bm3 going to be 599 when out (withouth bluetooth which is 240 I think).
Warranty-wise probably Dinan is the best. Smoothness - I bet bm3 since it's the complete flash (and burbles ). Raw power - jb4.
Still can't decide myself. Want to see bm3 numbers before anything though.
Hope this helps
